Benefits of technology

This patent text describes a new technique for printers that allows them to apply the right amount of energy to different types of dots on a print medium based on environmental factors. This helps to create better quality printing.

Problems solved by technology

Therefore, even in the print medium capable of developing the plurality of colors, it is not possible to change only the color development density of a single color.
Thus, for instance, when the quantity of energy to be applied to the print medium is adjusted for a color developable at a lower temperature in accordance with the environmental temperature, the known printer might apply an excessive quantity of energy to the print medium in an attempt to cause the print medium to develop a color developable at a higher temperature.

Embodiment Construction

[0023]It is noted that various connections are set forth between elements in the following description. It is noted that these connections in general and, unless specified otherwise, may be direct or indirect and that this specification is not intended to be limiting in this respect. Aspects of the present disclosure may be implemented on circuits (such as application specific integrated circuits) or in computer software as programs storable on computer-readable media including but not limited to RAMs, ROMs, flash memories, EEPROMs, CD-media, DVD-media, temporary storage, hard disk drives, floppy drives, permanent storage, and the like.

[0024]Hereinafter, an illustrative embodiment according to aspects of the present disclosure will be described with reference to the accompanying drawings. The drawings to be referred to in the following description are used to schematically show and set forth technical features according to aspects of the present disclosure. Nonetheless, the technica...

Abstract

A printer includes a controller configured to, based on print data, perform acquiring a condition value, calculating, for each type of dots, an additional period of time an=(Tn+Xn)−(Tn-1Xn-1), where Tn represents a specified period of time for applying energy to a heating element to form an n-th type of dot, Xn represents a correction period of time that is added to the specified period of time Tn to correct a dot formation condition of the n-th type of dot in accordance with the condition value, a heating period of time An for forming the n-th type of dot is obtained by adding the correction period of time Xn to the specified period of time Tn, and is derived from adding the additional period of time an to a heating period of time An-1, and setting the heating period of time An=Σk=1nak, for each dot included in a target line.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 U.S.C. § 119 from Japanese Patent Application No. 2016-190704 filed on Sep. 29, 2016. The entire subject matter of the application is incorporated herein by reference.BACKGROUNDTechnical Field[0002]The following description relates to aspects of a printer, a method, and a computer-readable medium for performing printing on a print medium using a thermal head.Related Art[0003]Heretofore, a printer has been known that includes a thermal head having a plurality of heating elements arranged in a direction perpendicular to a conveyance direction for a print medium. The printer is configured to perform printing on the print medium by repeating energization of the heating elements and conveyance of the print medium on a line-by-line basis. In the print medium capable of developing a plurality of colors, a color development condition of each developable color thereof varies depending on a quantity of energ...
